Glencore Sudbury INO
Glencore needed two high-capacity surface ventilation fans at its Fraser Mine to meet increased airflow demands for underground operations.
Each fan, rated at 2,250 horsepower, was designed to enhance the mine’s ventilation system and support Vale Canada Limited’s adjacent Coleman Mine. This project was crucial for expanding mining activities and ensuring compliance with air quality and safety standards.
SCOPE
BESTECH provided full-scope multidisciplinary engineering services, starting with detailed design and continuing to on-site construction support and commissioning. This included preparing tender documents, conducting bid reviews, and relocating equipment within an existing electrical building for two new Variable Frequency Drives (VFDs) and a new switchgear lineup. A heat study was conducted to ensure thermal stability, informing HVAC upgrades.
Additional engineering work involved installing dual parallel ventilation fans, high-pressure steel sectional doors, advanced instrumentation clusters, and a fully integrated power distribution and automation system. The demolition phase safely removed legacy fan systems, disconnecting electrical infrastructure and validating the structural integrity of remaining support systems.
OUTCOME
The project was completed successfully, increasing ventilation capacity for Fraser Mine and improving underground air quality and operational efficiency. The design also benefited Coleman Mine by meeting its airflow requirements. Through comprehensive engineering, project management, and commissioning, BESTECH integrated the new systems with minimal disruption to mining operations. The work was executed to high safety and reliability standards, reinforcing Glencore’s commitment to operational excellence.
